Evidence

POSITIVE
  • photo 1: structured vintage-style handbag with a hard semicircular top handle and metal frame closure
  • photo 1: brass-tone frame hardware and an interior zipper pocket are visible
NEGATIVE
  • photo 1: glossy black patent-like exterior is unlike the uncoated glove-tanned leather typical of classic vintage Coach
  • photo 1: no legible Coach wordmark, creed patch, horse-and-carriage, or recognizable Coach hangtag is visible
  • photo 2: the narrow framed clutch silhouette and patent finish do not closely match the listed classic Coach handbag models
  • photo 5: interior zipper area does not show a readable Coach stamp or creed
  • photo 6: the closure is a rectangular frame clasp rather than a typical vintage Coach turnlock
  • photo 1: interior zip area shows DOVER stamp, not COACH wordmark or creed patch
  • photo 1-6: black patent frame bag with kiss/clip frame closure and rigid top handle, not a catalog Coach silhouette
  • photo 1-2: black fabric lining with zip pocket, not unlined glove-tanned suede of vintage Coach classics
  • photo 1-6: gold-tone frame hardware with pitting/discoloration, no solid-brass Coach turnlock geometry
  • photo 1-6: no Coach creed patch, no Coach wordmark, no horse-and-carriage, no leather hangtag visible
  • photo 4: glossy patent finish, not glove-tanned cowhide
MISSING INFORMATION
  • photo 1-6: no clear close-up of the interior zipper pull or any maker label
  • photo 1-6: no straight-on close-up of all interior compartments and seams
  • photo 1-6: seller-stated 1960s age and Made in USA claim are not verifiable from the photos
  • photo 1-6: material composition is not confirmed; determine whether the patent exterior is leather, vinyl, or another synthetic
  • No Coach creed patch shown in any photo
  • No exterior front/back full view showing material and shape clearly
  • No close-up of interior brand stamp which appears to read DOVER in photo 1
  • No hardware brand stamps shown
AUTHENTICITY CONCERNS
  • ⚠ photo 1-6: construction and glossy patent finish are more consistent with a generic vintage frame purse than a Coach handbag
  • ⚠ photo 1-6: absence of any visible Coach identifier prevents support for Coach manufacture
